1. A method of bottom tracking, comprising the steps of:

  • transmitting a pulse through a medium towards a reflecting surface;

    receiving an echo of the pulse from the reflecting surface;

    convolving the echo whit the pulse thereby forming one or more convolution peaks on a convolution curve;

    processing the convolution peaks with neighboring convolution values so as to form an evaluation curve;

    searching for the highest peak on the evaluation curve; and

    comparing the highest peak to a threshold value.
